hmm I read 180 elsewhere hopefully i can solve this by just buying a 160mm and being done with it haha

nah I just looked it up the fork is supposed to take up to a 180mm rotor. I read elsewhere that with some rotors people where having clearance issues so hopefully carver just emails me back and has a solution

somebody else told me that the whub and o'beast don't work well together because the Carver fork (although advertised as a front offset) is somewhere between rear and front offset and isn't "correctly" designed

Carver Carbon O'Beat rotor clearance

I really liked the performance of my Carver carbon fork. I used it with a Salsa and a Hope Hub in conjunction with a White Brothers adapter. When I went finally put my Hadley (front disc spacing) hub into service, after removing the adapter, I had an interference issue. The Hope and Salsa were very close with the 5mm Bikeman adapter, one more than the other and I can't recall which one now. The guys at Bikeman were super great to deal with and let me return the fork.

I am using a White Brothers fork now. It's a little heavier but I can't tell when it is on the bike. I likely don't push the WB fork to anywhere near its "limit" so it works great for me. I now use the Bikeman adapters on my Hope and Salsa wheels. Now all three wheel sets can be swapped out without adjusting the brake.

A while back it was common practice to get a Hope Floating rotor to fit in a Fox fork, we had to file the thick white paint off the bottom post mount as the alu spider rubbed badly on the post and stripped the paint off marking the floating ano'd spider.

If you have 1mm clearance and are happy with the rotor it will work no worries.

My rotor was making contact down by the top barrel nut, same setup as you, .5mm spacer on the end of the hub did the trick. I have two wheel sets, both are WHub, one is fine the other needs the spacer.

I just put one on my Mukluk II from the latest batch Bikeman got and I was worried how close the roter came to the fork. Maybe this latest build group has slightly wider legs compared to previous batches. Once I got it adjusted it doesn't touch, but just barely.

"Thanks. For some reason, we see this occasionally with the Paul Whub.. It is perfectly OK to file the fork a bit for clearance. It won't affect the warranty. Other riders have also inserted a thin axle washer on the disc end of the hub to space it a bit farther from the fork."
